@Ego, ffj, Chad, tylerr - I recommend reading
A Hillbilly Elegy which just came out. Link to a lot of reviews. I also saw a very long interview with him but unfortunately I lost it. I haven't read the book yet but I have read a bunch of reviews and they confirm what I see in the my own personal collection of Trump voters (friends and relatives) which combined with their facebook exchanges with similars (ugh, research by anecdotal facebook references ... but hey, ...) ... leaving with a sample size of a few dozen in total and a handful up close.
So based on what I've seen about this collection, I agree that the Trump base is misunderstood by both liberals and conservatives. Here's my semi-informed understanding about the Trump base (as I know them):
Why liberals are wrong about the Trump base:
The Trump base (as I know them) is not anti-intellectual. Rather, they are complete non-intellectuals. It is true that most of them never read books. They might have a book collection of 1 or 2 books, total. Have they read them? (I asked). No, because they don't like to read. Do they dislike education? No, they're proud of their diplomas. Do they dislike intellectuals (such as me) or the intellectual statements I'm prone to make? No, they value them, but unlike liberals/intellectuals who would take me seriously insofar I appear that I know what I'm talking about, they take me seriously if and only if I'm part of their group (e.g. a relative). In general there's no desire to seek out nor retain intellectual knowledge beyond the point of getting by. Intellectually speaking, I knew more [intellectual] facts about the world by the time I was in 4th grade (e.g. how many planets in the solar system, where is Pakistan on a map, what happened on December 7th, how to do long division) than they do as adults. However, they are proud to be "paying the bills" even if they're economically struggling. This struggle has a lot to do with spending money on data plans (for cable and gaming), guns, pets, and car parts; and not so much on savings, mortgages, health insurance, and dental care. The solution here, for them, is to work harder and take a second job, which they'll then do, not to restructure their spending.
Liberals believe two things about the Trump base. 1) That their behaviour is due to lack of educational opportunities. 2) That their struggles can be fixed with handout programs. The Trump base resents this because (1) implies that ignorance is their primary problem but they don't believe that knowledge is the prime value (conversely, to a white-collar professional, knowledge is pretty much the only thing they value and they'd happily take the family cat to the shelter for a fancy career opportunity---well guess who adopts said cat? Yes, that's right.) And (2) implies that liberals believe that the Trump base can't take care of themselves or in the popular vernacular ("pay the bills") which is a very dishonourable position to be in.
Why conservatives are wrong about the Trump base:
Conservatives believe in moral agency. They believe that if you work hard on your business or your job and make smart choices---by which they mean follow conservative moral values which incidentally should be coded into legal law---anyone in America can succeed. Although the Trump base (as I know them) believe in working hard to "pay the bills", they do not believe that their hard work has any effect on the outcome of their life/situation. They do not believe in agency, at all. They are firmly convinced that the world is out to get them and screw them over. They often talk about how their co-workers and [former] friends are idiots. They encourage an in-your-face attitude and standing-up-for-yourself and your tribe. If someone insults your mother/wife/girlfriend, you punch them in the face. While that ethos worked well in past warrior cultures, you can imagine how it tends to get them laid off more often than not. A popular conversation topic is how many fist fights they've personally been in. They respect strong "warriors" who win confrontations. If such a leader is found they will back him up to a fault. Justice, morals, or being right matters much less than loyalty and winning. Their planning horizon, as far as I can tell, is about 30 minutes to a few hours. Resolutions made today will be broken tomorrow. One popular resolution is "to get out of this town" and "start over" but such plans are never acted on. As such, the main strategy for making big changes and the only chance to win at something is to buy lottery tickets. If they've seen a string of winners in city A, it's generally believed that the next winner will be in city B.
The Trump base differs from traditional conservative values by not believing in agency. Also unlike conservatives who believe that law is the source of order, the Trump base believes that strength is the source of order. Their primary desire is for a strong man who can give them the feeling of winning in life that they don't get from the lottery nor from their work experience. Typical conservative statements about working hard in order to succeed ring hollow when their personal experience has been one of being laid off over and over as other values (such as performance, personal behaviour, political correctness, ability to manage, ...) has increasingly taken a front seat to loyalty. What they want is not a party that promotes moral values that they must follow. What they want is to join a tribe behind a strong leader who can identify other tribes and win against them and thus set things right.
